防止埋地管道上浮的措施

Countermeasures against the Buckling of Buried Pipeline

埋地管道上浮是导致管道因受力不均而破裂的原因之一。埋地管道上浮的主要原因为浸水漂浮、土壤液化、膨胀土膨胀、冻胀抬起,提出了覆土、增设专用配重、深埋换土、保温隔离等防护措施,并介绍了具体实施步骤。

The buckling of buried pipeline is one of the reasons that results in fracture because of the uneven stress of pipeline. The main reasons of buckling of buried pipeline includes floation by water,soil liquification,swellable clay's swelling,and heave. The countermeasures against the buckling of buried pipeline such as backfilling,installing the special weights,soil replacement,and insulation as well as the construction program are presented in the paper.
